Water Withdrawal – Bathymetric Data

  • Bathymetry is a contour map of a water body.
  • Bathymetry is important to enable accurate

estimates of lake water volumes needed to ensure water withdrawals comply with the DFO winter water withdrawal protocol.

slide-8
SLIDE 8

7

Water Withdrawal – Bathymetric Data

  • DFO Protocol for Winter Water Withdrawal from

Ice-Covered Water Bodies in the Northwest Territories and Nunavut (June 2010).

  • To mitigate impacts to fish and provide standard

guidance.

slide-9

8

Water Withdrawal – Bathymetric Data

  • Paramount has stated that they believe that

bathymetric data provided exceeds requirements of protocol.

  • DFO has concluded that information provided for

Water Sources 1-3 is sufficient.

  • Additional information has yet to be provided for

Water Source 4.

slide-10

Water Withdrawal – Bathymetric Data

  • Data was obtained in 2002, operations planned until

2027.

  • Multiple activities over multiple sources
  • Operations conducted year-round, not limited to

winter operations.

Water Withdrawal – Bathymetric Data

RECOMMENDATION #1

  • All water sources should follow the DFO water

withdrawal protocol including Water Source 4 and any future sources.

Water Withdrawal - Quantities

  • Paramount has indicated that while they can’t

determine projected water withdrawal, they will follow the 10% withdrawal limit outlined in the DFO protocol.

  • Fish populations may be source specific.
  • Per source approach is consistent with protocol
slide-15

Water Withdrawal – Quantities

RECOMMENDATION #3

  • DFO recommends that the Water Licence limit

quantities on a per source basis as opposed to a per activity or overall limit and that Paramount report on these quantities to the Board on an annual basis to assist in tracking water use.

Water Withdrawal Quantities - Streams

  • Paramount indicates

that if streams are needed for withdrawal that 10% of instantaneous flow will not be exceeded as per existing operational statements.

slide-18
SLIDE 18

17

Water Withdrawal Quantities - Streams

  • Streams are especially susceptible to water withdrawal.
  • Winter conditions exacerbate impacts.
  • Protocol specific to water bodies.
  • Site-by-site assessment.

Water Withdrawal Quantities – Streams

RECOMMENDATION #4

  • DFO recommends that a condition in the Water

Licence limits water withdrawal to 10% of instantaneous flow

  • Notification and reporting should be provided when

streams are proposed as water sources

Water Withdrawal - Intake Screens

  • Paramount has stated that “water is withdrawn

according to Freshwater Intake End-of-Pipe Fish Screen Guidelines (DFO, 1995)”.

  • Fisheries Act – Section 30.
  • Mitigation measure of EA03-005.

Stream Crossings and Erosion

  • Paramount does not currently know the locations of

future crossings as locations of future well sites are undetermined.

  • DFO concurs that crossings can be reviewed during

Land Use Permit applications however standard conditions can be implemented through the Water Licence.

slide-27
SLIDE 27

26

Stream Crossings and Erosion

  • DFO believes the inclusion of mitigation measures

and the development of erosion and sediment control plan to be best management practices.

  • Erosion and sediment control is vital in ensuring the

protection of fish and fish habitat.

slide-28

Stream Crossings and Erosion

RECOMMENDATION #6

  • DFO recommends that the Water Licence include

standard sediment and erosion control conditions related to stream crossings including mitigation measures outlined in DFO’s various operational statements.

Stream Crossings and Erosion

RECOMMENDATION #7

  • DFO recommends that the Water Licence require

submission of a Sediment and Erosion Control Plan.

Monitoring and Reporting

  • Stream crossings can be a

source of sedimentation to streams.

  • Cameron Hills operations has

multiple crossing types.

  • Various potential impacts to

fish and fish habitat.

slide-37
SLIDE 37

36

Monitoring and Reporting

  • Paramount currently using Streamkeepers

Handbook.

  • Paramount feels that a more detailed monitoring

plan would provide little information regarding any potential impact as there is no point source discharge.

slide-38
SLIDE 38

37

Monitoring and Reporting

  • DFO believes that

Streamkeepers Handbook is currently being used incorrectly at Cameron Hills.

slide-39
SLIDE 39

38

Monitoring and Reporting

  • Monitoring needs to be reported to ensure that

mitigation measures are functioning as intended and capture environmental variation over time.

  • AEMP Guidelines provide consistency and

incorporate expectations of regulators and communities alike

  • Scale of predicted impacts = Scale of monitoring

Monitoring and Reporting

RECOMMENDATION #8

  • DFO recommends that TSS and turbidity sampling
  • ccur near stream crossings.
  • Tied into existing monitoring.
  • Upstream and downstream of crossings.

RECOMMENDATION #9

  • DFO recommends that the results be reported

annually including an updated map of crossings.

Monitoring and Reporting

RECOMMENDATION #10

  • DFO recommends that monitoring plans be structured as

suggested in existing AEMP guidelines.

  • AEMPs provide information and data to manage and

mitigate effects of development projects

  • Methodologies outlined in the Streamkeepers Handbook

could be integrated.
